Jan 07, 2013· Titanium is one of the most valuable elements found in blast furnace slag, with a concentration of approximate %. Because of the low level of titanium in slag, the best method of extraction is hydrometallurgy. In this study, parameters such as slag particle size, temperature, concentration of acid, solidtoliquid ratio, and ultrasonic wave time were used to determine the recovery of titanium.
offers 239 titanium slag products. About 9% of these are other titanium, 7% are titanium scrap, and 2% are industrial furnace. A wide variety of titanium slag options are available to you, such as is powder, not powder.
* The majority of components in Granulated Blast Furnace Slag are various glassy Metallic Silicates (Iron, Calcium, Magnesium, Aluminum, and Titanium Silicates), including: Dicalcium Silicate (Ca2SiO4), Merwinite (Ca3MgSi2O8), and Gehlenite (Ca2Al2SiO7) .

By additional energetic utilization of the off gases and the surplus char of the rotary kiln as well as the off gas of the electric furnace for power production the total energy consumption of the electric furnace per ton titanium slag can be further reduced to about 39% of the value in option A.
titanium concentration in hot metal by adding a significant amount of titanium raw material and controlling the furnace heat to a little higher level before shutdown with intensifying hearth cooling. 1. INTRODUCTION The main wear mechanisms for the lining of the hearth are abrasion caused by flowing hot metal/slag and corro

The invention relates to ferrous metallurgy and can be used in Ferroalloy industry, specifically in the production of low carbon ferrochrome. Various methods for the production of lowcarbon (refined) of ferrochrome in electric furnaces or spacegreat, allowing to obtain a low content of carbon in it, but they are inefficient and typically require the use of high quality materials.
by allowing increased carbon injection into the slag of electric arc furnace the (PeO) content in slag is decreased, and the quality of melting steel is improved [Ozawa et al 1986, Ameling et al 1986]. The rate of reaction between (FeO) in slag and carbon in slag plays an
electrode moving can not exceed 0,02 mis we failed in tapping the titanium slag produced in this furnace. The titanium slag managed to solidify before the rotation of crucible started. The approach to raw materials smelting by liquid slag results in stabilizing electrical energetic conditions for the process.
The applying of burden materials containing titanium compounds in the blast furnace process and the processes of forming titanium carbides and nitrides has a directly impact on the physical and chemical properties of slag and pig iron. Thereby affecting the course of the process, its efficiency and economy. It is known that the dynamic viscosity coefficient of slag – with an increased ...
A method of preparing a prereduced ilmenite ore for smelting, wherein metal oxides contained in the ore are selectively reduced in solidstate reactions over titanium oxide, the method including the step of prereducing carbonbased pellets of the ore.
For a furnace with basic refractories, which includes most carbon steelproducing furnaces, the usual slag formers are calcium oxide (CaO, in the form of burnt lime) and magnesium oxide (MgO, in the form of dolomite and magnesite). These slag formers are either charged with the scrap, or blown into the furnace during meltdown.
A method for the recovery of valuable materials from titanium grinding swarf is provided comprising the steps of sieving the accumulated titanium grinding swarf to remove unwanted coarse trash and grinding wheel fragments, pelletizing, and smelting in an electric arc furnace to produce ferrotitanium and/or high titanium slag.
As a result, the blast furnace titanium slag in CaTiO3 primary phase field contains less than 25% (mass fraction) TiO2, where the titanium resource cannot be recovered economically due to its low TiO2 content. Therefore, many other methods [5âˆ''12] are developed to achieve the comprehensive utilization of vanadium titanomagnetite ore.

Prereduction and DC openarc smelting of carbonbased ilmenite pellets K. Bisaka, I. Thobadi, and X. Goso Pyrometallurgy Division, Mintek The smelting of ilmenite to produce valuable titania slag and pig iron is an energyintensive process. At process temperatures of about 1700°C, roughly 1 MWh of electricity per ton of ilmenite feed is consumed.
Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
The furnace was lined with carbon brick and a rammed carbon hearth rather than with a normal refractory material, such as magnesite, to prevent excessive contamination of the molten slag by refractory oxides. Carbon was considered a less objectionable impurity than refractory oxides in titanium slag. Procedure and Results
